1. A method performed on a client computing device, the method comprising: receiving, by the client computing device from an on-line e-mail system, an e-mail that includes an attached document, where the received e-mail indicates a sender of the received e-mail and at least one recipient of the e-mail; opening, by the client computing device in response to a request by a user, the e-mail, where the user is one of the at least one recipients; presenting, by the client computing device from an on-line document system in response to the attached document being selected, an on-line version of the attached document, and where permissions were set on the on-line version in the on-line document system sufficient to allow reading and editing of the on-line version by the sender and by the at least one recipient; displaying, by the computing device in response to the presented online version being closed, a user interface asking the user if the user wants to send a reply to the received email with any changes made by the user to the presented online version; and sending, by the client computing device subsequent to the user indicating in the displayed user interface that the user wants to send the reply, the reply to the received e-mail, where the reply includes a link to the on-line version with the any changes.
